bug #7548 from Reinhard Max

Provide adequate documentation of the "table_name *" notation.

2012-09-17T18:59:38+00:00

Somewhere along the line, somebody decided to remove all trace of this
notation from the documentation text.  It was still in the command syntax
synopses, or at least some of them, but with no indication what it meant.
This will not do, as evidenced by the confusion apparent in bug #7543;
even if the notation is now unnecessary, people will find it in legacy
SQL code and need to know what it does.

Fix bufmgr so CHECKPOINT_END_OF_RECOVERY behaves as a shutdown checkpoint.

2012-09-16T18:55:27+00:00

Recovery code documents clearly that a shutdown checkpoint is executed at
end of recovery - a shutdown checkpoint WAL record is written but the buffer
manager had been altered to treat end of recovery as a normal checkpoint.
This bug exacerbates the bufmgr relpersistence bug.

Bug spotted by Andres Freund, patch by me.

Fix documentation reference to maximum allowed for autovacuum_freeze_max_age.

2012-09-16T17:20:35+00:00

The documentation mentioned setting autovacuum_freeze_max_age to
"its maximum allowed value of a little less than two billion".
This led to a post asking about the exact maximum allowed value,
which is precisely two billion, not "a little less".

Based on question by Radovan Jablonovsky.  Backpatch to 8.3.

Back-patch fix and test case for bug #7516.

2012-09-14T15:50:06+00:00

Back-patch commits 9afc6481117d2dd936e752da0424a2b6b05f6459 and
b8fbbcf37f22c5e8361da939ad0fc4be18a34ca9.  The first of these is really
a minor code cleanup to save a few cycles, but it turns out to provide
a workaround for the misoptimization problem described in bug #7516.
The second commit adds a regression test case.

Back-patch the fix to all active branches.  The test case only works
as far back as 9.0, because it relies on plpgsql which isn't installed
by default before that.  (I didn't have success modifying it into an
all-plperl form that still provoked a crash, though this may just reflect
my lack of Perl-fu.)

Properly set relpersistence for fake relcache entries.

2012-09-14T13:39:10+00:00

This can result in buffers failing to be properly flushed at
checkpoint time, leading to data loss.
